Brief Summary
The goal of this observational study is to investigate the relationship between functional magnetic resonance imaging (fMRI) findings of the brain and symptom presentation in patients with bladder pain syndrome (BPS). The main questions it aims to answer are:
- 1.To explore the distribution characteristics of fMRI imaging and possible target lesions in the patient population.
- 2.To provide appropriate clues and evidence for etiological exploration and therapeutic targeting of BPS.

Outcome Measures
Primary Outcomes (1)
fMRI findings
The fMRI is acquired using a Siemens 3.0T MRI scanner. BOLD functional images are scanned using an echo planar imaging (EPI) sequence. The scanning parameters are: TR=2s, matrix size of 64\*64, number of layers=30, layer thickness=3.75\*3.75\*4.5mm, and bottom-up interval scanning. A total of 540 whole brain functional images are acquired. The relevant data acquired from fMRI should undergo the following pre-processing before generating findings: (1) data format conversion; (2) temporal layer correction; (3) head movement correction; (4) normalization; (5) smoothing
1 day (fMRI is performed once upon the recruitment of the study subject.)
Study Arms (2)
BPS group
Patients with BPS (subject to current diagnostic criteria and clinical guidelines).
Control group
Patients with symptoms of bladder pain and evidence of current urinary tract infection.
Interventions
The fMRI is acquired using a Siemens 3.0T MRI scanner. BOLD functional images are scanned using an echo planar imaging (EPI) sequence. The scanning parameters are: TR=2s, matrix size of 64\*64, number of layers=30, layer thickness=3.75\*3.75\*4.5mm, and bottom-up interval scanning. A total of 540 whole brain functional images are acquired.
